MOTOR-DRIVEN APPARATUS.

Application led August 26, 1919. Serial No, 320,019.

To allwho'm t may concern.'

Be it known that I, JAMES CLAYTON, a subject of the King of Great Britain, residing at 12 Middlesborough Road, Coventry, in the county of Warwick, England, have invented new and useful Improvements in Motor-Driven Apparatus', of which the following is a specification.

vMy invention relates to apparatus employed in the manufacture of artificial silk, according to what is known as the Topham system, wherein viscose, or the like, is ejected from a nozzle into a setting bath and the threads formed are led under and over suitable guiding devices and down through a thread-guide, or funnel into a rapidly rotating spinning-box in which the thread is coiled and the object of my invention is to overcome certain objections incidental to such apparatus as hitherto constructed.

In such apparatus I have found tha-t the best results cannot be obtained unless, during the operation of the apparatus, proper alignment kbe maintained between the axes of the spinning-boxes and their spindles and` the thread-guides, or funnels, through which the threads pass before they enter the spinning-boxes.

This maintenance of alignment is not satisfactorily attained by supporting the spinning boxes and their adjuncts in the manner hitherto practised and it is one of the objects of my present invention to provide means which will effect and maintain such alignment and allow the spinning-boxes to be adjusted with facility and maintained in true position.

The spinning-boxes, as hitherto made, are perforated around their periphery and there is a large hole in the top, or cover, of the spinning-box for the passage of the threadguide,.or funnel, this hole being made large to avoid contact of this part of the box with the saidv thread-guide, or funnel, owing` to deviationA of the box from alignment with surrounding them and through the thread (laden with chemicals) coiled in the said boxes, whilst they are in operation, is detrimental and results in the formation of large quantitieslof corrosive vapours, or gases, which are injurious to the apparatus and injurious to health and another object of my invention is -to overcome this objection.

Further, when the spinning-boxes are driven by electric motors mounted on the spindles of the said boxes, it Yis an advan tage tok maintain the motors as near normal temperature as possible and it is a further object of my invention to effect this.

According to my invention true alignment of the spinning-boxes, and their spindles and motors, with the thread-giudes, or funnels, is practically effected by iiexibly mounting the motor-casings (or some equivalent part in connection with the spinningbox spindles) on three, or more, adjustable resilient supportsI (which I will refer to as spring supports) so that the openings in the top of the spinning-boxes, through which openings the thread-guides, or funnels, pass, can be. made so small, or fit around the sides of the thread-guides, or yfunnels, so closely, as to prevent the circulation of the aforesaid large volumes of air through the spinning-boxes and thespace surrounding them, and therefore overcome the objections consequent thereon and I, by this means, so utilize the exhausting effect due to the rotation of the perforated spinning-boxes as to maintain, during the operation of the machine, a partial vacuum in the said boxes which obviates, or greatly lessens, the formation of injurious vapours, or gases, from the chemicals carried over into the boxes by the threads, and allows such chemicals to pass away as liquid for re-use if desired.

I also provide means by which air is caused to pass in contact with the electric motors carried by the spindles of the spinning-boxes, so that the said motors are prevented from becoming overheated and are thereby rendered more eiiicient .and durable.

I will describe, with reference'to the ac- I of so much of a machine as is necessary to illustrate the application of my invention thereto.

Figure 2 is a vertical section of a rail and one of the motor-casings, and means whereby its flexible mounting for proper alignment and regulation and fixing in proper position, are effected. Figure 3 is a vertical section across the rail between two spinning-boxes shewing the motor-casing in elevation, and Figure 4 is a plan. Theseligures also shew the passages for air to prevent overheating of the motors.

Figure 5 is a vertical section shewing the arrangement of the passages for air, modified for application to the rail which is moved up and down when the machine to which my invention is applied is one in whichthe spinning-boxes are reciprocated as well as rotated.

Figures 1 and 5 are drawn to a smaller scale than that to which Figures 2, 3 and l are drawn.

Each spinning-box 1- is perforated around its periphery as indicated, for example, at l, and is mounted,'as usual, on a spindle 2,

,l which carries the rotor '3a of an electric motor 3, (not indicated in Fi ure 3) the stator 3b of which is carried by t e casing. t, which encloses the motor and has bearings d" and d", at top and botto-rn, in which bearings the spindle 2, rotates against ball-bear 'f ings above, the bottom-end of the spindle Ito 2- being cupped and resting on a ball 6, whichv bears upon another ball 7, which is received in a cup in the end of the adjusting screw 8 which can lbe locked in its adjusted position by the lock-nut 9 bearing against the end of the motor-casin stem 10., which passes through an opening in the rail 11, the said end of the stem being screwed and provided with an adjusting lock-nut 12 and spring, or springwasher 12Q1 whereby the pressure upon the spring supports can be simultaneously regulated and the vertical'position v ofthe motor-casing and other parts be adjusted.,

' The motor-casing fl, has three feet cast upon it at 13, each of which restsupon an inverted cup 1d. lThe rail 11, carries three corresponding'stems 15, which can be adjust* ed (by a spanner applied to thejhead 15a) in screwed holes in the rail 11, and be fixed in theadjusted position by the loch-nuts 15b. 'llhe upper ends of the stems 15, enter the inverted cups la, which each contain a y spring 16.

Each thread-guide, or funnel, 17, pret.

erably consists Vof a glass, or like, tube open I. 'at top and perforated at its lower end,

through which the thread,'from the godet above, is passed, in the usual way, into the spinning-box 1, the said tube being. enclosed in an outer tube made of acid-proof metal. For bearing against, and reciprocating on, this outer tube the top of each spinning box is provided with a packing-box 20, whichfcontains any suitable packing 20, a suitable packing for this purpose being wood' saturated with lubricating oil.

Owing to the closure of the box, or the restriction of its opening, around the threadguide, or funnel, and to the centrifugal force set up by the high speed of the box there is, when the machine' is in operation, always a partial vacuum within the box and the hitherto objectionable formation of vapours, or gases, and the circulation thereof, with the air, through the boxes and ,the space around them enclosed by the easing, 25, is prevented, or greatly lessened, with the beneficial effects hereinbefore mentioned.

rlhe motors are cooled by air supplied to them, or drawn into their casings, so that a current of airl passes between the-rotors and stators of the motors. This is shewn in the drawings as being eected by forcing, or drawing, air through the rails 11, which are, at l1, made hollow for the purpose the hollow communicating, by passages 11b, with a channel 11, through which' passes one of the stems 15, of the -Aaforesaid-spring seatings for the motor-casings, this stein being prolonged at 15, for the'purpose, `the prolonga- Figure 5 shews an arrangement of airpassages suitable in cases where the rails 11, carrying the spinning-boxes and their adjuncts, are reciprocated as well as rotated, the rails carrying tubes 28, sliding in the tubular part 'of a bracket-piece 27 securedto a hollow supporting bar 26. rllhe air is passed, or drawn, into the interior 2ta of the bar 26, and passes, by the openings 26", into the space 27a in the part 27, and thence, by the openings 28a and 28b in the tube'28,lto the passage l1, and channel llc, in the rail 11, and thence, by the opening 15d, in the stem 15, to and through the motor as described with regard to the arrangement shewn in the other figures. in both arrangements the course of the air is indicated by arrows. l
